I shall now link you to a playlist of an album full of uptempo Disney songs.
Some of the songs are a bit weird (IMO), and it's from Japan, so you'll have to have an open mind in the styling of some of the music, but they're all dance tunes, so PERFECT for working out to. I loved it so much I actually searched and bought the actual cd for this in Japan. It's pretty in real life, all holographic and such.
Here you go:

PS: My absolute favorite is the "Part Of Your World" remix.
